eric-haibin-lin opened a new issue #14264: nd.reshape truncate values
URL: https://github.com/apache/incubator-mxnet/issues/14264
 
 
   reshape with a smaller shape truncates the value in the tensor, which is strange and inconsistent with numpy:
   ```
   >>> import mxnet as mx
   >>> a = mx.nd.arange(10)
   >>> a
   
   [0. 1. 2. 3. 4. 5. 6. 7. 8. 9.]
   <NDArray 10 @cpu(0)>
   >>> b = a.reshape((1,2))
   >>> b
   
   [[0. 1.]]
   <NDArray 1x2 @cpu(0)>
   >>>
   ```
   whereas in numpy:
   ```
   >>> import numpy as np
   >>> a = np.arange(10)
   >>> a
   array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])
   >>> a.reshape((1,2))
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
   ValueError: cannot reshape array of size 10 into shape (1,2)
   ```
